Combining new technology with classic taxonomy to overcome hurdles to discovering dark taxa

Systematics and Biodiversity, Journal Year: 2025, Volume and Issue: 23(1)

Published: Jan. 31, 2025

With numerous perils threatening biodiversity, we must remember that most of the basic units biodiversity—species—remain unknown and therefore difficult to assess. Hordes new species continue be discovered described every year. As each requires extensive work, completing description Earth's biota could require millennia, leaving many wanting automate process via genetic barcoding artificial intelligence. Over time, lesser-known groups species, referred as 'dark taxa', will occupy an increasing proportion awaiting description. dark taxa have few barcodes or images for matching algorithms, however, I propose integrating traditional taxonomy into automated workflows by linking data verified specimens using classic taxonomic keys decision trees identifying images. The roles intelligence would thus limited until can build databases specimens. This strategy vital their scientific names so signify undiscovered which is lacking in current methods.

Phylogenetics and Evolutionary Dynamics of Yunnan Acrididae Grasshoppers Inferred from 17 New Mitochondrial Genomes

Insects, Journal Year: 2025, Volume and Issue: 16(2), P. 151 - 151

Published: Feb. 3, 2025

Yunnan Province, a global biodiversity hotspot, hosts diverse array of Acrididae grasshoppers essential for ecosystem dynamics and agriculture. To elucidate the phylogenetic relationships evolutionary history this group, we sequenced analyzed complete mitochondrial genomes from 17 species endemic to Yunnan, with genome lengths ranging 15,403 15,943 base pairs. These data were integrated sequences 46 additional construct comprehensive trees. The maximum-likelihood tree identified four major clades robust support (bootstrap values > 90%), revealing significant lineage diversification during Early Eocene (51.94 million years ago, Mya) subsequent radiations in Miocene (~20 Pliocene (~5 Mya). divergence times correlate geological events climatic shifts region, such as uplift Tibetan Plateau intensification Asian monsoon. Notably, several within Coptacrinae Oxyinae subfamilies, particularly Pseudodotraulia cornuata Spathosternum prasiniferum, found be polyphyletic, indicating necessity taxonomic revisions. Further cluster analyses codon usage bias genetic distance these revisions Acrididae. This framework underpins conservation strategies aimed at preserving Yunnan’s rich grasshopper informs updates their phylogeny.

Distribution Patterns of Platycodon grandiflorus From the Last Interglacial Period to the Future by Ecological Niche Modeling

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(4)

Published: March 30, 2025

ABSTRACT Global climate change may represent a significant threat to the distribution and quality of medicinal plants, altering cultivation areas compromising medical materials. Platycodon grandiflorus , traditional Chinese herb, has millennia‐long culinary use history in East Asia. Given its escalating demand, accurately evaluating changes under different scenarios predicting potential are imperative for ensuring conservation sustainable utilization. By integrating MaxEnt with ArcGIS, this study advances previous approaches by incorporating historical, present, future data model dynamics P. across China. The results indicated: (1) species' strongly correlates environmental variables, particularly bio13, prec07, prec09, tmin07, whose cumulative value percent contribution was 78.5%; (2) centroids geographic during LIG, LGM, MH periods were situated further westward compared present distribution, substantial contraction observed highly suitable habitats throughout these historical periods; (3) Under climatic conditions, overall habitat encompasses 4,185,964 km 2 constituting one‐third expanse, predominantly concentrated central, southern, northeastern China; (4) Future predict that total will expand varying degrees (7% increase on average), albeit reductions (3% decrease average); (5) is likely move toward higher latitudes due changes. Our findings fill critical knowledge gap quantifying impact . These offer crucial insights developing effective strategies, promoting utilization, establishing standardized protocols resources.

This study analyzes the impact of iNaturalist on recording and documentation fungi in Chile from 2008 to 2024, highlighting its role integrating citizen science into biodiversity monitoring. community effort—which currently totals more than 63,000 observations representing 1,245 species—is concentrated central southern regions country, mainly urban areas, where a small group hyperprolific users generates 44.40% records. Since 2020, an increase number has been observed, which may be linked growing interest mycology. The use allows overcoming traditional logistical limitations, expanding taxonomic, spatial, temporal coverage fungal observations, but these advantages are not without biases. In addition, mycology faces structural challenges, such as funding training new specialists. Collaboration between amateurs professional mycologists is essential validate data extract potential this type tools. approach complements conventional methods studies strengthens conservation policies.
